NOAA-21 VIIRS satellite data provides global binned measurements of Particulate Organic Carbon concentration in the ocean surface. The dataset is produced by OB_CLOUD and uses algorithms from Stramski (2007) and Stramski et al. (2022). This version is identified as 2025.0.
Use Cases
- Modeling surface carbon stocks using the 'poc' concentration variable.
- Conducting biogeochemical studies by analyzing 'poc' alongside other suite variables like chlor_a and SST.
- Studying ecological contexts by correlating 'poc' data with features such as bbp and Kd_490.
- Supporting export-flux studies through spatial and temporal analysis of the global 'poc' field.
Strengths
- Global spatial coverage from the NOAA-21 VIIRS satellite sensor.
- Includes a specific geophysical variable for Particulate Organic Carbon (poc) with defined units (mg C m⁻³).
- Algorithm version is specified (Stramski, 2007/Stramski et al. 2022 for PACE).
Limitations
- Specific row count, temporal range, and spatial resolution are unknown.
- Data is limited to surface ocean measurements derived from ocean-color reflectance.
